26 Claims.

This invention relates to lining machines. It is particularly directed to a machine" for lining can caps or other articles with liquid sealing material.

An object of this invention is to provide a machine of the character described, which feeds the can caps or other articles to be lined, at regular intervals, rotates each cap about its axis and dispenses sealing material onto the cap only as the cap rotates, and has means to prevent discharge of sealing material if a cap is not fed into position to receive the sealing material.

A further object of this invention is to provide in a machine of the character described, means to synchronize the rotation of the caps-with the discharge of the sealing material to the cap.

Still another object of this invention is to provide a strong, rugged and compact machine of the character described, which shall be rela tively inexpensive to manufacture, smooth and positive in operation, and practical and eiilcient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

Fig. 9 is a view similar to Fig. 4, but showing a machine embodying the invention, illustrating a modified construction;

Fig. is a cross-sectional view taken on line ill-l0 of Fig. 9;

of parallel, upstanding, vertical frames l2 and The frame ['2 has a top wall I4 formed with a central opening l5, and an offset opening l6. Fixed to the top wall It, as by screws l1, and supported thereby, is a circular plate l8, having a central opening [9 registering with opening I5, and an offset opening 20 aligned with the offset opening l6.

Extending through the openings I5 and i9, is a vertical shaft 22 projecting above the plate l8. Fixed to the shaft 22 is a collar 23 extending within the opening l5 and contacting the underside of the circular plate l8. Fixed to'the upper end of the shaft 22 is a collar 24. Re-

. ceived on said shaft, and below the collar 24,

.is a boss 25 fixed to said shaft by a set screw. Fixed to the underside of the boss 25, and

-' resting on the circular plate It, is a circular plate 26 formed with a plurality of equiangularly spaced openings 21 of somewhat larger diameter than the openings l6 and 20, and adapted to successively register with said openings when said plate is rotated about the axis of shaft 22.

Means is provided to intermittently rotate the shaft 22, and hence the plate 26, through equal angles similar to the angles between the openings 21. To this end, there is fixed to the lower end of the shaft 22, a Geneva gear 30 having as many radial, equiangularly spaced slots as there are openings 21 in plate 26. Rotatably supported within the frame I2 is a vertical shaft 3| having a pawl 32 at its lower end cooperating with the Geneva gear 30. At the upper end of shaft 3| is a bevel gear 33.

Journalled within the frame l2, in any suitable manner, is a horizontal drive shaft 34 carrying a beveled gear 35, meshing with the beveled gear 33. The shaft 34 is driven by any suitable power means to rotate the shaft 3|, and hence to intermittently rotate the shaft 22 and plate 26, to successively bring the openings 21 into registry with openings I6, 20 at regular intervals.

Means is provided to feed the caps Ina, or any other articles to be lined, or to receive a liquid sealing material applied thereto in the manner hereinafter appearing, to openings in the plate 26. The feeding means may be similar to the mechanism shown in my co-pending application, Serial No. 248,741, filed December 31, 1938, for Work feeding de ice.

As shown in Fig. l, the feeding means generally comprises an upwardly inclined chute 46 adapted to slidably receive the caps Illa, and a suitable support 4|. Mounted on the chute 40 for transverse sliding movement thereon, is a plate 42 formed with an inclined by-pass groove 43 on the inner face thereof. Slidably mounted in one end of plate 42 is sheath member 42a having a pin and slot connection therewith, a spring being interposed between member 42a and one end of the plate. Pivoted to the frame I2, is a lever 44 connected to the frame by a coil tension spring 45. The upper end of the lever is connected in any suitable manner to the member 42a.

On the shaft 34 is a face cam 46 engaging a roller 41 at the lower end of the lever 44. As the shaft 34 rotates, the lever 44 is oscillated to reciprocate member 42a and hence the sliding plate 42, to permit the caps to come down the top wall of the frame.

the chute through by-pass groove 43 one at a time. The lever 44 is synchronized with the rotation of the plate 26, to permit one cap to drop down to the plate each time the plate is rotated to bring another opening 21 to the lower end of the chute.

Means is provided to lift and then rotate each cap as it is brought by the plate 26 to a position above the opening 26. To this end, there is fixed to the shaft 34 a gear 50.

Journalled on the frame l2 and I3 is a horizontal shaft 5|, parallel to and aligned with the shaft 34. Carried by the shaft 5| is a gear 52 meshing with the gear 50. Fixed to the shaft 5| is a lift cam 53 disposed directly below the openings l6 and 20. Slidably mounted in the frame I2 is a member 54 carrying at its lower end a wheel 55 contacting the cam 53. Fixed to member 54 is a horizontal pin 56, passing through a vertical slot 51 in the frame [2. Attached to the pin ,56 is a cross-bar 58, interconnected by a pair of coil tension springs 59 to pins 60, fixed to the frame and disposed below said cross-bar.

It will now be understood that the springs 59 tend to press the member 54 downwardly to keep the wheel 55 in contact with the lift cam 53. As the shaft 5| is rotated, member 54 is reciprocated vertically.

Mounted in the frame l2, in any suitable manner, for vertical sliding movement; as well as rotation, is a spindle 65, connected to member 54 by a rotary thrust bearing 66 and formed in its upper end with a socket opening or recess 65a, for the purpose hereinafter appearing. The spindle 65 reciprocates with member 54.

Means is provided for continuously rotating the spindle 65. To this end, there is journalled in frames I2 and I3, in any suitable manner, a horizontal shaft 66 carrying a bevel gear 61 meshing with a bevel gear 68 splined to the spindle 65. Shaft 66 is connected by sprocket chain gearing 10 to the shaft 5|.

It will now be understood that when the drive shaft 34 is rotated, the caps will be intermittently fed to the openings 21 in plate 26. The plate 26 will intermittently carry the caps to a position above the openings |6 and 20, and the spindle 65 will be continuously rotated and also reciprocated upwardly through the opening 26. When the spindle is down, the plate 26 rotates. When the plate 26 is at rest, the spindle moves up and then down. When the spindle 65 moves upwardly, it lifts the cap Illa above the spindle and rotates the same, for the purpose hereinafter appearing.

As shown in Fig. 12, the cap |||a shown herein for the purpose of illustration only, comprises a bottom wall 12, an upwardly extending annular flange 13, and an outwardly and downwardly inclined flange 74. Between the flanges 13 and 14, is a channel or trough 15. The caps Illa are fed in inverted position, that is, with the bottom wall 12 at the top.

Means is provided for spraying a liquid sealing material into the channel 15 while the cap la is in lifted position and is being rotated by the spindle. To this end, there is attached to the top of the frame I3, a bracket |3a having a pair of aligned slots 16 receiving screws 11 screwed to The slots 16 are in a vertical plane passing through the axis of shaft 22 and the axis of opening 26 or in a plane parallel thereto, whereby said bracket |3a may be adjusted toward or away from said opening.

The bracket |3a is provided with a boss 18 having a vertical bore 19 to receive the lower reduced end of a vertical post or rod 80. On the post 66 is a collar 6| adapted to be fixed thereto in vertically adjusted positions by a set screw 8 la.

Rotatably mounted on the post 80, above the collar 8|, is an annular ring clamp 82 having an offset sleeve 62a receiving said post and contacting collar 8|, and adapted to be fixed to the post by a set screw 82b. Supported within and fixed to the clamp 82 is a vertical tank 83 containing the liquid sealing material. The top of the tank may be closed by an air tight cover 34, whereby the tank may be provided with compressed air above the liquid sealing material.

By loosening the set screw 821), the 'tank may be swung about the axis of the post 86. On the ring 8| is a vertical upwardly extending stop pin 8|b which serves to limit rotation of the tank in one direction. The tank may also be swung out of the way, to a position where it is not used, as illustrated in dotted lines in Fig. 3 of the drawings.

At the lower end of the tank is a downwardly converging conical wall 85 formed at its apex with an internally, screw threaded, downwardly projecting nipple 86. Screwed to the lower end of the nipple 86 is a vertical pipe 81 formed with a central vertical through opening 88 communicating with the bottom of the tank. The lower end of the pipe 81 may be closed by a screw plug 90. The lower portion of the pipe 81 is formed with a downwardly and outwardly inclined, conical outer surface 9|, for the purpose hereinafter appearing. Said lower portion of the pipe 81 is formed with a downwardly and outwardly inclined thin opening Bla communicating with the opening 88 of said pipe.

Rotatably mounted on the surface 9| of pipe 81, is an annular ring 93, having a tapering inner surface 94 corresponding to the tapering outer surface 9| of said pipe. The ring 93 is formed with an inclined screw threaded socket 96 and with a downwardly and outwardly inclined thin opening 91, which in one angular position of the ring registers with the opening 9Ia. Screwed within the socket 96 is a downwardly and outwardly inclined nozzle 91a formed with a as shown in Fig. 5 of the spindle 65. When the spindle lifts the cap, and

the ring is in the angular position shown in full lines in Figs. 4 and 5, openings 9Ia and 91 register and the material within the tank passes through the openings 9Ia, 91 and 98 to the channel I5 which receives the sealing material as the cap is rotated. When the ring 93 is rotated to disali'gn openings 9Ia and 91, the-discharge of liquid is immediately stopped.

Means is provided to control the angular position of ring 93 for initiating the flow of sealing material to the channel I5 as soon as the cap is lifted, and to shut off the flow of sealing material when the cap is lowered, and to prevent any sealing material being discharged if there is no cap on the spindle.

To this end, there is clamped to the ring 93, a split clamp 93a having radial ears 93b clamped together by a screw 930. The clamp 93a is formed with a radial projection 99 carrying an upwardly extending pin 99a, for the purpose hereinafter appearing. On the ring 93 is a thrust roller bearing 99c, pressed down against the ring 93 by a coil compression spring 99d, interposed between the thrust bearing and the lower end of the nipple 80.

On the frame I2 is a vertical upwardly extending pin I00. Rotatably mounted on the pin I00, is a horizontal arm IOI formed at its outer end with a vertical through opening in which is slidably mounted a vertical pin I02, co-axial with and disposed above the spindle 65. Fixed to the upper end of the pin I02 is a collar I03. When there is a cap on the upper end of the spindle, and the spindle is lifted, the cap will lift the pin I02. As the spindle 65 is lowered with a cap thereon, the pin I02 will likewise be lowered. However, if there is no cap on the upper end of the spindle, the lower end of the pin I02 will project downwardly into the opening 6511 as the spindle is lifted, and the pin will not be lifted.

There is further fixed to the frame I2 a vertical pin I06 on which there is mounted a member I01 formed with a pair of spaced vertical walls I08 forming a slot I09 therebetween. Fixed to the walls I08 is a transverse pin I I traversing the slot. .Received within the slot I09, and pivoted to the pin I I0 is a lever III having one end formed with an opening II2 disposed directly above the pin I02 and the axis of spindle 65.

, Screwed within the opening H2 is an adjustable vertical pin II3 adapted to be contacted by the pin I02 when the latter is lifted by a cap on the spindle. If a cap is lifted, the pin I02 will rotate the lever II I in a clockwise direction looking at Fig. 1 of the drawings, for the purpose hereinafter appearing.

Mounted on the frame I3 for rotation about its axis, is a vertical non-slidable shaft II5. Fixed to the upper end of the shaft H5 is a horizontal member II6 comprising a pair of parallel vertical walls III and H8, and a bottom wall II9. Between the walls III and H9 is a The lower end of the opening 98 may slot I20. Within the slot I20 is a lever I2I pivoted at one end by a transverse pin I22 traversing the slot I20.

Interposed between thelever I2I and the bottom wall H9 is a coil compressionspring I23 which normally tends to lift said lever. One end of the wall I I0 is formed with a vertical through slot I25, for the purpose hereinafter appearing.

The front end of the bottom wall'II9 is cut away, as at I I9a, and the lower edge of the front portion of the vertical wall III is likewise cut away, as at IIIa.

The pin 99a on clamp 93a normally projects into the slot I25. Said pin 99a is aligned with the cut away portions 911 and II'Ia in the bottom wall H9 and the side wall I". When there is no cap on the spindle or when the spindle is down and the pin I02 is not lifted, the spring I23 will raise the lever I2I to the position shown in Fig. 8 of the drawings, above the upper end of the pin 99a, and member I I6 may be oscillated without turning ring 93.

Means is provided to oscillate the shaft II5 about its axis. To this end, there is fixed to the shaft 34, a face cam I34 contacting a roller I35 on an arm I36 offset from the shaft H5. The arm I35 is connected by a coil tension spring I3'I to the frame I3, to retain the roller I35 in constant contact with the face of the cam I34.

It .will now be understood that as the drive shaft 34 rotates, the shaft II5 will be oscillated in synchronism with the operation of the feeding mechanism'and rotation of the plate 26. The ring 93 is normally in the dotted line position of Fig. 4,- with the openings 9| and. 91 disaligned so that no liquid is discharged. If there is no cap on the spindle, lever I2I is lifted by spring I23 above pin 99a and the shaft II 5 oscillates member II6 without affecting the position of the ring 93.

The lever III has an offset arm I IIa overlying the lever I2I, If there is a cap on the spindle, as the spindle is raised the cap will lift the pin I02 to rotate the lever III for pressing the lever I2I downwardly, against spring I23, below the pin 99a. Said pin is then disposed between the forward end of the wall H8 and the forward end of the lever I2I. As the shaft II5 oscillates member II6 to the full line position shown in Fig. 4, the ring 93 will be moved to the full line position shown in Fig. 4 to bring nozzle 91a directly above the channel I5 in the lifted cap, and register the openings 91 and 98 with the opening 9I to permit the sealing material to pass said channel of the rotating cap. As the arm H6 is oscillated in an opposite direction back to the dotted line position of Fig. 4, the ring 93 is rotated in a clockwise direction to disalign the nozzle in the opening 91 relative to the opening 9|, to shut off the supply of sealing material.

It will be understood that the oscillation of the arm H6 is synchronized with the operation of the machine so that it begins to rotate in a clockwise direction, after the spindle is lifted, whereby the nozzle 91a can only be moved to dispensing position when a cap is lifted by the spindle.

Fixed to the top of frame [3 is a stop member I40 having vertical portions I4I carrying an adjustable stop screws I42, adapted to contact one of the radial projections 93b of the clamp 93a to limit angular rotation of said clamp in one direction.

It will be noted that by fixing the set screw 821), the tank 83 may be rotated to the inoperative tions.

3 upon the cap as soon as the openings 61 and 6Ia overlap. 'As the nozzle continues to move and the two openings progressively increase their overlap, the compound continues to spray upon the cap. Since the nozzle is spaced from the cap, a small arc of movement of the nozzle through which the sealing liquid is sprayed causes the spray to cover a larger angle at the point of application. Thus, the spraying may start even before the liquid touches the cap and a the spray may continue as the nozzle passes back and forth, causin the spray to continue across the rim of the cap. This spraying action spreads the liquid and thereby distributes the same evenly to prevent coagulation in spots.

With the present construction, there is no dripping in one spot, as for example, in com structions in which the nozzle is stationary. The spraying may begin before the stream of liquid reaches the cap and may continue until the sam is entirely off the cap.

By loosening the nuts 11, the bracket 16 may be adjusted to accommodate caps of various sizes. By loosening the screw 63c and. turning the ring 63a relative to the rotary valve 63, the amount of liquid dispensed may be varied, so that the machine may be used with equal effectiveness for small caps requiring a smaller amount of sealing liquid, and with large caps requiring a greater amount of sealing liquid.

In Figs 9, l and 11 there is disclosed a machine I42, embodying the invention, and illus-- trating a modified construction. In the machine I0 of Figs. 1 to 8, the nozzle carrying member 93 was rotatable to operative and inoperative posi- The machine I42 is similar to the machine I0, with the exception that in the former, the nozzle carrying member is stationary, an inner rotary valve or cock being provided, together with means for rotating the same to operative and inoperative positions, as will be explained in detail hereinafter.

To this end, there is screwed to the nipple 66 of the liquid tank 63, a member I43 having a nipple I44 at its upper end received within the threads of the nipple 66. Member I43 comprises an annular portion I45 carrying said nipple I44 and fonned with an axial conical bore I46, and with a vertical passage I41 interconnecting the bore I46 with the nipple I44.

Extending downwardly from member I45 is a boss I48 formed with an internally screw threaded socket I49. Member I43 is furthermore formed with a vertical narrow passage I50 establishing communication between the socket I49 and the 'bore. Screwed to the socket I46 is a nozzle II pointing downwardly toward the channel 15 of a cap Ila on the spindle 65.

Rotatably mounted within member I46 is a valve or cock I54 having a frusto-conical portion I56 disposed within the bore I46. Extending from said portion I56, is a horizontal, axial portion I59, from which there extends a reduced ing I56a. Said portion I56 is furthermore formed with a downwardly extending vertical passage I56d communicating with the opening I56a.

As shown in Fig. 11 of the drawings, in one position of the valve, passage I56 registers with passage I41, and passage I56d communicates with passage I50. In such position, liquid from the tank will pass through the nozzle to be discharged to the channel 15 of-the rotating cap when the spindle 65 is lifted. However, upon rotating the valve member I54, in the manner hereinafter appearing, to disalign the passages I56d and I56, the discharge of liquid through the nozzle is immediately cut oil.

The valve I54 is normally in inoperative position. Means is provided, however, to rotate the valve I54 to operative position, only when there is a cap on the spindle and the spindle is lifted. To this end, there is fixed to valve I54, a horizontal arm I62 having an opening at one end receiving the reduced portion I60 and fixed thereto by a nut I63, screwed to the stem I6I. On member I56 is a ball thrust bearing I66 pressed against portion I45 of member I43 by a coil compression spring I61 interposed between said thrust bearing and the arm I62.

Slidably mounted on the arm I62 for longitudinal movement, is a plate I10. Fixed to the plate I10 is a horizontal, outwardly extending pin M, for the purpose herein after appearing. The outer end of the arm I62 has a finger I1I parallel to the plate and disposed therebelow. When the plate I10 is moved outwardly in the manner hereinafter appearing, the outer end of the plate is parallel to the finger I1I forming a slot I12 therebetween.

On the frame I3 of the machine is a vertically, upwardly extending pin I15 carrying a bracket I16. Pivoted to the bracket I16 is a lever I11 having one end I16, disposed directly above the spindle 65. On the arm I16 of the lever is an adjustable screw I60, adapted to be engaged by the pin I02 on the arm IN.

The lever I11 has a second arm I62 formed with a slot I63 concentric with the axis of the valve v I54 and receiving the pin I10a of the plate I10.

It will be noted that the pivot I11a for the lever I11 is disposed below the arm I62 and closer to the pin I10a, than the axis of the valve I54.

On the pivot I11a. of the lever I 11 is a torsion spring I86, 'normaly tending to rotate the lever I11 in a counter-clockwise direction, looking at Fig. 10, to retain the screw I in contact with the pin I02.

On the drive shaft 64 is a face cam I60. Slidably mounted on the frame I3, in any suitable manner, is a vertical rod I 6| disposed directly above the face cam. The lower end of the rod II is retained in contact with the face cam by a coil tension spring I62 interconnecting the rod with the frame. At the upper end of the rod is a pin 164 normally received in the slot I12. As the machine operates the rod II is reciprocated vertically.

If a cap is disposed above the spindle 65, and the spindle is lifted, lever I11 will be rotated in a clockwise direction, to a position shown in Fig. 10 of the drawings, for moving the plate I10 outwardly to the position shown in full lines in Fig.

Upon lifting the rod I 6|, the valve I54 will be moved to position for registering the opening I56d with the opening I50, and the opening I56c with the passage I41 to permit discharge of liquid may reciprocate without rotating the valve.

to the cap. When the rod I! is lowered-the valve becomes disaligned to cut' off discharge of liquid. Thereafter, the spindle 65 is lowered.

Should there be no cap on the spindle, the

lifting of the spindle 65 will not raise the pin I02, and the lever I'll will not be rotated in a clockwise direction, and the plate IIII will not be slidably moved outwardly, and then the rod I9I It will thereforebe seen that unless thereis a cap on the spindle no liquid will be discharged from the tank.

It will now be understood that the tank may be raised or lowered by adjusting the position of the collar M on the post 80 to accommodate caps or other articles of various sizes lifted by the spindle 65. Furthermore, the bracket I3a may be adjusted to bring the nozzle 91a in correct position depending upon the diameter of the cap or other article lifted by the spindle.

It will be observed that the ring 93a may be loosened by loosening the screw 93c and the ring may then be rotated relative to the rotary member 93, through a small angle, and then again tightened thereon. Such adjustment will vary the registration of the openings 9Ia and 91 from full registration to partial registration. Thus, the amount of liquid discharged each time the valve is rotated to discharging position may be varied so that the machine can be used for smaller capsas well as large caps. Likewise, as shown in Fig, 11, by loosening the nut I53, the arm I62 may be varied angularly with respect to the rotary valve I54, so that in discharging position,

the registration between the openings I56 and I50 can be varied from full registration to partial registration, likewise varying the amount of liquid discharged each time the valve is in discharging position.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above setforth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
